Name
LVPECL/LVDS/HCSL/Dual CMOS Function
1
OE
Output Enable. Internal pull-up for OE active high. Pull-
down for OE active low. See ordering information.
2
FS
Frequency Selected.
0 = First frequency selected.
1 = Second frequency selected.

CLK+
Clock Output.
5
CLK–
Complementary Clock Output.
6
V_DD
Power Supply Voltage.
2.1. Dual CMOS Buffer
Dual CMOS output format ordering options support either complementary or in-phase output signals. This feature
enables replacement of multiple XOs with a single Si512/13 device.
